SAP Note 15391 - KEU1/KEU2: Selection of field group for tracing factor

Symptom:

When you press F4 on the field group, not all the value fields of the operating concern are displayed.

Cause and prerequisites

The number of the field group only has one character, so only nine value fields can be selected.

Solution
In Release 2.1x, only the first nine value fields of an operating concern can generally be selected as a tracing factor. In Release 2.2x, only the first ninety-nine value fields can be selected as a tracing factor. If you want to use other value fields, you must enter a digit different to 0 in the column RC of table T811J. The digits must however be uniquely assigned to the value fields, that is, 0 must be entered for other value fields.
Key to the affected entries:
CE7nnnn U I xxxxx (nnnn - operating concern, xxxx - name of value field)
